Introduction. Hematite and magnetite iron ores are the most prominent raw materials for iron and steel production. Most of the highgrade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO).
This present paper discusses both the dry and wet magnetic separation techniques used for processing of a low grade siliceous iron ore sample. The investigations carried out on low grade iron ore fines reveal the following: 1. The low grade iron ore fines contain around 45 % Fe, % SiO 2 and % Al 2 O 3. 2.
The samples were subjected to jigging, dry low intensity magnetic separation (DLIMS) and shaking table tests. ... A., Mohanty, M. K. 2007.
